Screen Gone My screen went blank and has not returned. I have checked all inputs and they seem fine. I have switched from HDMI 1 to HDMI 2, no luck. Volume and signal seem fine, I simply have no picture (on ANY input). The screen is back lit but is essntiall black. There are no shadows or anything. It's as if the video feeddies but everything else works.

I cannot "reset" to factory settings as I cannot see the screen or operate the menu to do so. Also, all power settings are working. Let me clarify. I'm listening to CNN right now. It's just that there is nothing, I mean nothing coming through the screen output but backlighting. There is no picture. Menu controls even do not appear.I cannot "reset" to factory settings as I cannot see the screen or operate the menu to do so. Also, all power settings are working. Let me clarify.

The stand by light works and flashes three times before turning on...just as it always has. Honestly, wth the exception of no picture signal, just a black (but lit) screen, the T.V. works EXACTLY as it did before. I can listen to the t.v. as if it were working fine. In fact, when it stopped working I didn't notice. My back was to the t.v. the sound was working and when I turned around, there was no picture.The stand by light works and flashes three times before turning on...just as it always has.

Actually, the backlight works just fine. There's no video feed from the T.V. Not the receiver, but the T.V. itself. That's why I can't even see the control graphics.

Am I totally hosed here? The warranty just expired too.Actually, the backlight works just fine. There's no video feed from the T.V. Not the receiver, but the T.V. itself. That's why I can't even see the control graphics.

Tuner box has been un plugged before. It is again, but this seems as if what I'm dealing wit here is a dead video card...as in it simply died. Where do I go to fix that nd what kind of cost am I looking at?Tuner box has been un plugged before.

I am at my wit's end here and your (and that of the expert who mentioned the video card) opinion makes the most (and most unfortunate) sense.

i like to play my xbox and after about 30-45 minutes of playing the tv turns black. but i can still hear my xbox and all the sound, just no picture. i have found that if i leave my tv off for about 15-20 minutes, when i turn the tv back on, the picture works. but then the tv's picture shuts down and i have to repeat the process.

there is a faint illumination but no picture just a "lit up" black screen, audio seems finethere is a faint illumination but no picture just a "lit up" black screen, audio seems fine

It sounds as though the backlight has failed or shutdown for some reason. You can confirm this by putting a flashlight against the screen and seeing if there is any picture visible. The fact that no OSD or menu is visible leads me to think that you have no backlight. However, if you can see that screen is lit, then don't waste you time trying this. Hope this helps.

So you DO have a backlight but no picture. With no OSD or menu showing, the only things left are the video process board or the panel (and the TCON board). The TCON board is the address board for the panel which tells which pixels to turn on. On some sets, the TCON board is supplied with the panel, on others it can be replaced separately. Has to be one of the two. Unfortunately you will need a technician to narrow it down for you. Sorry I couldn't be of further assistance.

Here are my suggestions for finding service. Choose a servicer that is au authorized provider for Toshiba products. Avoid the places the promise free estimates as they tend to get their money from you in other ways. I wouldn't suggest you just buy a video board and try and put it in yourself; if it's the panel that's failed, you'll be stuck with a video board, since most places won't take back parts that have been used. If you have further questions, please feel free to ask. I'm here to help in any way that I can.

Bappa, May I ask why you are suggesting polaroid parts for a Toshiba unit?Norcodad,Since the warranty has just expired, I would not hesitate to contact Toshiba to see if they will offer some type of accommodation on the repair. Many times, the manufacturer will offer to pay parts, labor or some portion thereof. Hope this helps.

You neeed to try to reset hdmi setting , turn off the tv for a min. , turn back on tv then turn back hdmi settings , if resetting the hdmi doesn't work un hook all connected cables , turn off tv and unplug from the wall , leave unplugged for a half hour at least , then try again. if all this don't work then a component inside is failing and will need testing or the video board replaced

if theres a reset button on the back off the set press it , if not then you have to unplug all cables shut down the tv unplug it for a while , if that don't work then it needs repairif theres a reset button on the back off the set press it , if not then you have to unplug all cables shut down the tv unplug it for a while , if that don't work then it needs repair

any other video inputs on the tv may also be causing no video , make sure nothing is hooked up then do a reset of tv , if it still will not give you video , then it for sure needs repairany other video inputs on the tv may also be causing no video , make sure nothing is hooked up then do a reset of tv , if it still will not give you video , then it for sure needs repair

The TV is going in protect mode because it detects an internal problem, try leaving it unplugged for a longer time, let say one hour or two.
Basically, what happens is that the TV does not start because it detects that there is an internal problem, such as a wrong voltage, a bad component, overheating etc.When you unplug power and restart it, you reset the internal circuit, and the TV will restart, not detecting the internal problem.As soon as the TV gets hot, after staying on for a while, the defective part start giving troubles, as the defective component (probably an IC, starts overheating).

As already pointed by the other expert, from description, the digital processing board. can be cause for the problem as there is no video. However all the following parts can be involved.

Check that the TV is set to the right input. Maybe it should be on HDMI 1, and it got changed to HDMI 2, for example. Try a different source. If you're watching Satellite, switch to your Blu-Ray player. Check that your source is on, too.

Tries to reset the tv Tuner board back to factory setting.By go into the tv menu.Go to PICTURE,go down to reset the Tuner board.All the HDMI ports should work now.Not,than the HDMI port 2 is shorted and dead,don't used the HDMI port 2.The tv should work fine,or tries websites like Shopjimmy.com,Ebay.com to buy a refurbish Tuner board for the replacement.

What I did was initally hook up both the composite (R/W/Y) cables and the HDMI and switched between TV inputs until I found the display. Once I had the display (mine was on composite) I went to the settings, then display, and switched it to HDMI input. The screen went blank and I switched to my HDMI TV input and saw the display. I unplugged the composite and it was good to go. I also had to hold my finger over the power button for a few seconds when turning it on - I believe it resets the display to default, but it worked. Good luck!

In the event that it gives you a hard drive error shortly after, it's nothing to worry about. You won't lose anything and it will take a few minutes to run its course. Just make sure you never turn it off from the back of the system first, always shut it off via menu options.

I had this problem when I connected to the hdmi input
I called and was told the set had to be readjusted for the hdmi input it was still under warrentee.so the sent a tech out to readjust the set and have never had this problem again........

I would first try changing the inputs if there is an HDMI cable connected the PS3 will detect it and change the output to HDMI.
Make sure when you connect any HDMI cables that the power is off on ALL Units that are using HDMI.
Connect the cables then power up all units.
Change TV and Receiver or Amp to correct HDMI Inputs.
On the PS3 go to Display Settings over to the left of the Crossbar.
Select output settings and select HDMI and everything after select AUTOMATIC!
Then Set your Audio (Also use Auto) and Save by pressing X.
Good Luck!

I had the same problem (a flashing HDMI 1 text box in the upper left hand corner of the screen every +/- 10 seconds) and rebooting the cable box seemed to help. I'd previously tried disconnecting and reconnecting the cables, but wasn't successful. I assume my problem originates with Time Warner Cable.
